Britney Spears takes Vegas!

Britney Spears has a major announcement this morning, and let's just say your next trip to Vegas might be a lot more Toxic than usual.

Wayne Newton, Cher, Céline Dion, Elton John and now Britney Spears: They are pop legends who have all wound up with lucrative Vegas gigs. The blond bombshell just announced that she is taking on a two-year residency in the City of Sin!

In a special appearance on Good Morning America, the former The X Factor judge flew in via helicopter to announce the news to a horde of screaming fans and said her performances will be housed at Planet Hollywood.

"We wanted the environment to be that way so people could come and have a good time and stand up and feel like they’re in the show with me," Spears explained. "I love Vegas. The energy here is really, really good."

She really does love Vegas: The star had a rep back in the day of partying her tail off there and even staged a spur-of-the-moment wedding to childhood friend Jason Alexander during a wild weekend wearing jeans, a belly top and a trucker hat, only to have it annulled 55 hours later.

Getting to the venue to make the announcement itself may have been more nerve-wracking than any stage fright the stage veteran might get — she later tweeted the news to fans and said she was terrified of flying in the helicopter.
